Louis mhrnnrnn'rm or Los ANGELES, cALrFoRNIA To all whom it may concerne a citizen'of the United States, residing in the city of Los An eles, county of Los Angeles and State of aliforn-ia, have. invented new and useful Improvements iii VHeating Apparatus, of which the following is a speci- 4fica-tion.

My invention relates to improvements in.. 'apparatus used for .heating dwelliiifr lhouses or other structures in which the fue usedis gas or otherv vapor'fuel, and the 'object thereof ist'o -produce a simple efficient and economical apparatus for'that purpose which willlheat t e airwithout contaminating the same by `anyof the roducts of combustion.

I accomplish the o ject thereof bythe apparatus described herein and illustrated in the accompanying drawings in which;

Figure l is an end elevation partly in v proved' apparatus. Fig. 2 is a side elevation r partly in sectionand partly broken away, of

my improved apparatus.

'In thefdrawings the outer casing of the jacket is composed vof a /sheet iron body 5 .which may be lined with asbestos if desired. NearL the bottom the outer jacket is perforated by perforations 6 through which the air for all purposes passes, into what may be termed theY air distributing chamber 7. lTo the top of theo'uter jacket -are'connected the conducting lilies 8 which carrythe heated air to the -places of use not shown. -Within the outerfjacketand suitably s aced therefrom are batteries of radiating ues 9 which are open at the, bottom into the combilistion chamber 10, andv are closed at the top. top portions of these Vfines are broaderthan the lower or body portions. The hiliet portions abut against each other an project Vover the space which separates the battery,-

' of fiuesfrom the' adjacent one.

In the drawings I have shown three baitteries of lines, each battery'being composed' of eight iiues, but.any number of fines may be used'." Below each battery ofl flues is a .combustion'chamber 10which extends longitudinally underlthe flues. The combustion chamberhasv perforations 11 in the bottom thereof vthroughl which. the vprincipal amount .of air used for combustion passes. Extending .longitudinally through the combustion chambers are gas or vapor burners 12 of any therebyv provi The -f be heated is divided into a considerable nu 'HEATING AFPARATUS.

These `openin s are connected by apipe ing a cased opening into each l combustion chamber from the front .end thereof. These openings Yare=covered bya hinged door 20, which is provided .with

screened openings 21 opposite or in registerl I with each openingi'nto the combustion chamber. These openings and door provide convenient means'for lighting the burners and inspecting the interior' of the combustion chamber.
